I have been getting into these charming Mediterranean-climate terrestrials, and have had some successes. My own mentor has been a nearby orchid grower, Scott McGregor, who was interviewed on the subject in a recent
Orchid Digest (see if you can beg, borrow, or buy the April/May/June 2019 Vol 83-2
Orchid Digest)
I use a mix that is about 80%-85% inorganic (I like pumice rather than perlite, to give the pots enough weight to not tip over). The balance can be a fast-draining potting soil such as cactus mix mixed with chopped sphagnum, seedling-size coconut chips, or seedling bark. A few chips of marble are also advantageous - very slow-release calcium carbonate, since these grow in calcareous soils. I will start watering once the weather cools off - for me, probably late October. The first shoots will probably emerge about 6-8 weeks after that, and bloom in the spring. Once they die back, stop watering. Scott suggests white pots, which stay cooler in the sun - these need strong sun for at least a few hours a day, even when dormant. (That's my biggest challenge, my yard faces north and doesn't get a lot of sun in winter)
If you want to get a look at my "success experiences" take a look at my website
Orchidcentral.org, scroll down until you find them. There are some other genera in the group (and some Australian terrestrials as well, slightly different mix) I have been growing these for about 3 years, success rate improving.
